The insects native to Asia usually nest in open places like tree tops, whereas European hornets nest in dark places like roof spaces. They also fly at night, whereas Asian hornets never do and are not active during this time.

Although all hornets look similar to wasps and bees, a hornet sting is more painful because their venom contains a larger amount of acetylcholine.

If you're allergic to wasp venom, then you'll also be allergic to hornet stings.
